According to the company, the BlackHole RAT release is still under development, and appears to be using the source code of a popular Windows trojan horse known as darkComet.

I have full controll over your Computer and I can do everything I want, and you can do nothing to prevent it. So, Im a very new virus, under Development, so there will be much more functions when I'm finished. But for now, it's okay what I can do. To show you what I can do, I will reboot your Computer after you have clicked the Button right down.
